To ZZ whom t may concern:

le it known that I, RONALD F. MCFEELY, a citizen of the United States, iesiding at Beverly, in thecounty ot Essex and State of Massachusetts, have invented certain Improvements in Sliiiiil Beiitiiig Machines, which the following descriptiomrin connection with the accompanying drawings, is a specification, like referencel characters on the drawings indicating like parts in the several figures.

This invention relates to machines for use in the manufacture of boots and shoes and more particularly to a machine for shaping the shank portion of the shoe to conform the sole to the transverse contour of a thick shank stii'ener applied to the bottom of the innersole of a lasted shoe. The usual method of shaping the shank portion of the shoe consists in beating or pounding the shank portion of the sole with a hand hamnier to reduce the soleto correspondence with the contour of the stiii'ener. lVhen operating upon shoes which are provided with the cottage roof forni of stitener, that iS, a stitt'ener having a sharp ridge extending along the longitudinal median line of the stitfener. it is especially hard to conform the sole tothe stili'ener by the hand hammer. Stitfeners ot this'type are extensively used in the manufacture ot' womens turn shoes, and the. shank of such a shoe, when conformed to thel stitlener, slopes toward the sole edge upon each side of the Vmedian line. In performing this operation with a hand hammer considerable care has to be used that the shoe is not injured by too violent or misdirected blows which would tend to break down the stiiiener or be liable to strain the sole attaching stitches. This method is also slow and requires considerable time for what is a minor operation.

One object of the present invention is to provide mechanical beating means which will conform the shank portion of the sole to the stiti'encr in such a manner as to obviate they above. enumerated disadvantage ot the hand method.

.\n important feature of this invention consists iii the combination with a support by which the shoe is movable to present either side of the shank alternatively in a selected plane, of a beater arranged to strike the shoe with a slight inward component ot its movement directed away from the edge and means for actuating the beater to do its work.

Another feature of the invention consists in means for so operating the beating means that it is rapidly vibrated and operates on the shoe with a succession of uniform blows. A resilient connection between the beating means and the operating means gives a yielding blow to the beater or hammer and compensates for the variations of the sole at the shank. This yielding connection, prefeably, as herein shown, comprises a piston and cylinder interposed between a -ibrating hammer and a crank shaft on the machine. Resilient material,V preferably of slight compressibility, is located iii the cylinder of the said connection and acts on the reciprocating piston in such a manner that a connection between the beater and its actuator is` established, which, while substantially positive, is yielding enough for the purposes above set forth.

The shoe is supported during the beating operation by a jack which is so mounted that the shoe may be moved in such manner that the portion being acted upon may be maintained always in substantial alinement between its point of support and the beating means. The jack possesses certain features of novelty which form part of this invention.

These and other features of the invention, including more important details of construction and combinations of parts will be explained in the following description and pointed out in the claims.

Figure l is a side elevation ot a shank beating mechanism embodying the present invention; Fig. is a side view in elevation showing the position of the hammer on the shoe in operation: Fig. Q is a section-.il detail; Fig. 3 is a perspective view ot the piston and cylinder connection; Fig. l is a trout view ot the. upper portion of the inachine: Fig. 5 is a detail ot` the heel post: Fig. (i is a detail otl the actuating means.

leterriiig to the drawings, a column l carries at its upper part a head 3. This head is formed with two upriglits 4 in which is journalcd the crank shaft 5. The crank shaft 5 has fast on its outer end a disk member Fig. l, which coperates, as a friction member, with a'loose pulley S, thus forming the fast and loose members of a friction clutch mechanism. The loose pulley S is mounted to rotate freely upon the shaft 5 and is movable axially of the shaft toward and from position to engage the fast member 6. An ear i) on the frame of the machine provides a bearing for a rock shaft 16 having an arm l() which is connected by a rod 1J: to a foot treadle (not shown). The rock shaft has on its rear end an eccentric pin 1S, which carries a shoe 15. The shoe stands in a groove 12 in the hub of the loose pulley S, as shown in Fig. 6. The depression of the treadle partly rotates the shaft 16 in the bearing 9 thereby moving the shoe l5 by means of the eccentric pin 13 in the direction to force the loose pulley 8 into frictional engagementwith the fast pulley 6. j A'spring pressed rod 20 which passes through a lug on the frame of the machine acts on the arm to return the loose pulley 8 to an inoperative position when the treadle is released. f Two arms 227 Fig. 4, extending upwardly from the head of the machine provide a bearing for the pivoted beater' or hammer 24. and also a shoe guard. The hammer 2i, Fig. l, is in the -form of an L-shaped lever having a beating face at one end and pivoted near to its other end between the upwardly extending arms 22 by a pivot pin 28. A bifurcated member pivoted to the lower end of the hammer 24C is connected to one end of a piston rod 32. This piston rod has a head portion 33 which is confined in a. cylinder 3l. Said cylinder is pivotally mounted at its rear end upon an eccentric or crank 39 on the shaft 5 by a plate 36 and bolts 37 shown in Fig.

Resilient material .LO, which may be rubber in suitable form, is located inthis cylinder on both sides of the head 33 of the piston and iills the spaces between said head and the end of the cylinder on one side and the head and an adjustable stopper on the other side. rl`his resilient material completes an approximately positive connection between the crank shaft 5 and the hammer 2st but yieldingly restricts the reciprocation of the piston in the cylinder. By reason ofits resilient qualities this material will yield to the piston suliciently to compensate for such variations of the work as the hammer will encounter during the beating operation. The use of this yielding material also causes the hammer to deliver a light rebounding blow.

The machine frame is provided with a projecting bearing 42 to the outer end of which is connected the spindle etat of the work support. The spindle 14C is shown as the sole to the transverse made in two sections t and 16, the section 46 being formed as a sleeve pivoted at its lower end to the bearing` 42 and threaded to receive the threaded lower portion of the spindle 44, the spring pin 17 in the sleeve 46 preventing accidental rotation of the jack. The spindle 4l is guided loosely through a bracket 8 which is adjustably secured in the frame by a binding screw 4t2). A hand wheel 50 mounted on the said spindle provides for vertical adjustment of the jack. A member 52 having a tubular portion adapted to it over the upper end of the spindle and free to turn thereon has a` pair of upwardly extending arms 54 which support a block 58 pivoted between the upper ends of the arms 5l. The carriage 56 is mounted on the block 58 by a curved slot or guideway 59 for movement longitudinally of the shoe and carries a toe pad 60 and a heel post 62 to support a. shoe on the last during the operation of the machine thereon. The toe pad 60 is mounted for vertical adjustment in the upper end of an arm 61 which lis pivoted to the carriage at 65 below and back ofthe pad and has a. spring pressed latch 66 which7 operating with a ratchet plate 68 on the carriage, adjusts the rest 60 upwardly and backwardly, or ieversely,\vith relation to .the heel post 62 for different sizes of shoes. A thumb screw 70 provides vertical adjustment for the rest 60 in the arm 64 to bring the curvature of 4the shank of the shoe substantially parallel to the guideway 59 of the carriage so .that the face of the hammer will not strike at an angle to the sole.

The heel post 62 is mounted in a member 72, in which it is held by the split clamp and screw 79. The member 72 carries a stud y7l which is journaled in a part 77 `for movement about an axis which extends longitudinally of the shoe. The part 77'lies between and is pivoted to ears 75 by a pin 73 which also engages a notch in the stud 71 to prevent withdrawal of the stud, the notch being shaped to permit a limited rotation of the stud 7l and hence a` lateral movement of the post 62 about the stud as an axis to allow the shoe to be tilted at the proper angle for the shank portion of curvature of the shank stiffener. A lug 74 depending from the heel pin supporting member 72 rests by a rounded face on a spring pressed plunger 76 in the carriage to keep the toe of the shoe pressed down upon the toe pad. Movement of the pin 62 by the plunger 76 is limited in one direction by contacting faces at 8l formed respectively upon the part 77 and the ears 75. The toe pad 60 is mounted for hammer to conform the movement like the heel pin about an axis 6l extending longitudinally of the shoe and preferably substantially parallel to the bottom of the forepart thereof.
